YARN GUIDE FOR KNITTING MACHINES.

Application filed Kay 21,

Fig. 4 is a view of one of the guide tubes detached.

. In these drawings 1 indicates a yarn guide adapted to be attached tothe reciprocating carrier barof a Cotton frame. Its lower end is splitand-spring tempered. The opposing faces 2 of the lower split end of theyarn o guide are grooved as shown and these grooves have inclinedbottoms resenting jointly a receiving socket formation which is flaredtowards its upper end. In this socket-like formation a yarn guide tube 3is mounted. It is tapered to fit the recess between the ends of thesplit guide andas its upper end is of a diameter larger than its lowerend, it will be retained in place merely by the rip of the ends 4, 4 ofthe ggsplit member t ereon. It can not become displaced nor dislodgedfrom between these ends by a lengthwise movement because of its upwardflared formation or its eneral taper, it being understood that the saidtube may be tapered from end to end or said taper may extend only partway of the length of the tube. In order to place the tube in position itis pressed laterally between the jaws 4, 4 of the split member. Thesejaws will spring apart sufiiciently to allow the tube to be sna ped intoplace, and a suitable implement li e a pair of pliers may be employed tosnap the tube into position. The jaws 4, 4 have an enlarged recessbetween their upper ends at 5, rendering the jaws more resilient byreducing the thickness of the upper ends of said jaws.

There is a groove 6 extending vertically along the front face of theguide for the passage of the yarn to the tubular insert guide piece 3.This tubular member 3 projects below the lower end of its holder.

When a tube'3 becomes worn it is removed and its place is taken by a newtube. In placing a new tube in position it is forced 1927. Serial No.193,279.

between the spring aws 4, 4 by pressure exerted in a direction laterallyof the main body of the uide. That is to say, the new tube is placesidewise against the old tube and when pressure is applied to the newtube 1t 18 force in between the jaws and the old tube is forced out frombetween the jaws.

The renewal can be made quickly, and no fastening means is necessary tohold the tube in place, thespring grip of the jaws and the tapered formof the seat between the aws being all that is necessary to insure theholding of the tube in place. At its upper end the tube abuts theshoulders 7 forming the upper wall of the socket or grooves between thespring jaws 4, 4.

- In a previous form of guide,,a removable cylindrical tube has been emloyed which issoldered in place between at facedjaws. When this is to berenewed, the solder must be melted and thenew tube inserted andresoldered. This takes much time. Renewal of the guide tube isnecessitated by the wear of the yarn. When silk is used the guide tubeis soon out by the continued action of the silk yarn thereon and renewalof the tube then becomes necessary.

I claim:

l. A yarn guide havin spring jaws, a guide tube snapped into p acebetween said aws and sha ed to prevent endwise remova1, substantia ly asdescribed.

2. A yarn guide having spring jaws with grooves in the opposing faces ofsaid jaws, and a guide tube snapped laterally into place between saidjaws and flared externaly to prevent longitudinal displacement orremoval, substantially as described.

3. In combination in a yarn guide for full fashioned knitting machines,a member havng spring jaws with grooves in their opposmg faces, saidgrooves being enlarged at one point and presenting shoulders at theirupper ends, and a yarn guide tube held between said jaws in the groovesand against the shoulders, and having an enlarged portion to fit theenlargement] of the grooves to prevent lengthwise dislod ment of thetube, substantially as describe 4. A yarn guide having spring jaws, aguide tube snapped into place between said jaws, said jaws and tubehaving coacting surfaces shaped to prevent endwise removal of said tubein both directions.

5. A yarn guide consisting of a depending 1!.

plate like member comparatively thin throughout its lower portion andterminating in spring jaws at its lower end, and a guide tube locatedbetween said spring jaw-s and disposed with its axis intermediate thefront and rear faces of the jaw portion of said thin plate-like member.

6. A yarn guide having spring jaws havnig a normal tendency to springtowards each other, a guide tube between said jaws,-

with means for holding said tube in said jaws against longitudinaldisplacement in either direction.

In testimony whereof, I allix niy signature.

KENNETH HOWVIE.
